The Schedule referred-to in these-Letten Patent and making part of the aama `To all whom it may concern:

Be it known that I, LEMUEL PowELL, of Milford,

in the county of New Haven, and State of Connectient, have invented a new and improved Railroad Smoke-Conveyer; andl do hereby declare that the following is a full, clear, and exact description thereof, which will enable Vothersskilled in the art to make and use the same, reference being had to the accompanypg drawings, forming part of this specification, in whic 'Figure ljrepresents a vertical longitudinal section of my improved smoke-eonveyer.

Figure 2'is a plan or top view of the same.

Figure 3 is a detail longitudinal section, on an enlarged scale vof' the same.

Similar letters of reference indicate corresponding parts. l

The object'of this invention is to prevent the smoke and ashes issuing from the smoke-stack of a locomotive from entering the cars of the train, and thereby preventing the proper ventilation of the cars.

The passengers on` railroad trainsare, by the smoke and cinders, frequently prevented from opening the` windows of the ca1's,`in order to obtain fresh air. To

prevent this inconvenience, it has been 'frequently proposed to conduct the air and cinders back over the train in pipes, tted upon the cars. Such process has, however, been found `inconvenient for vari- `ous reasons, chiey, however, because Athe draught of the locomotive was thereby reduced; also, because the height of the cars was increased, preventing them with the crank c of .a shaft, E, which is operated` by the engineer. rEhe latter can thereby open and close the damper at will. e

From the smoke-stack projects backward a'pipe, F,

ported on one side ofthe tender.

Thepipe on the tenderjs connected with a pipe, H, on the roof of the car behind'it.

Every car is provided with two pipes H H, one on each side. y

Thefpipes, being on the sides, do not'reaeh above,

y which is coupled together with apipe, G, that is supysage is to be' disconnected.

at least not much above the higher middle part ot' the car-roof, and do 'not, therefore, prevent the cars from passing under arches, to which they were previously adapted.

The reason for` arranging two pipes on each car is to enable the cars to be reversed, and still to be connected with the pipes G and vF.l

` The ends of each pipe G and lH are enlarged, and an elastic pipe, I, is secured in the rear end of eachl pipev G H, so that such pipes I serve to connect the others.

Each pipe I is smaller than the enlarged front end of the pipe H, into which it is fitted loosely, so that air may ieely enter the outer annular part of such pipe H.

When the train is in motion, the damper a beingV closed, the smoke and products of combustion pass all into the pipe andthence into G `and H, and are 'thus conducted Vover the train'.

The air not only freely enters the front ends of the pipes G H, but also that of the pipe F, which, for this purpose, is left partly open, as shown in tig. l.

The smoke, as it passesE through the aforesaid varions pipes, is, by the air, which enters the open front ends ofthe pipes, rapidly propelled through the same.

The draught is thereby made perfect.

When the train is not in mot-ion, the damper a is opened, to let the smoke escape in the ordinary man ner.

Owing tothe rapidity of motion with which trains pass through the air, the latter is caused to enter the pipes F G H with considerable force, so as to push the smoke out, and thereby to produce a draught of greater power than that obtained inwthe open smokep stack.

An inclined pipe,- J, projects downward from the pipe G, either to the ground or vinto a water or other reservoir .provided on or under the tender.

All cinders that may enter the pipes F G will,.in

the pipe J, be 'conducted to the ground, and will thereby be prevented from accumulating in the other passages H. .A

The pipes I- are forced backward, by springs e, into the pipes H offthe hind cars, and can, by suitable strings or chains-f, be drawn forward when the pas? lhe elasticity of these pipes 'allows them 'to yield to up and down as well'as lateral motions of the cars,

, Withou't interrupting the connection.

That row of pipes H, which is not connected with the smoke-stack, has the pipes I at the front ends, as i 4in"ig. 2, so that the same will be in rear when the cars are reversed.

Theconnection between the pipes F Gmay be direct, as shown, `without anjelastic pipe, I.

new

ducting-pipes, arranged, as described, in al horizontal line below the top of the highest car, but above the window thereof, for the purpose set forth.

4. In combination with pipes to transfer end discharge the smoke behind the moving train of cars, as set forth, an inclined pipe, J, located on the tender7 to receive the cinders, and convey them to the ground,

lor some receptacle, in the manner described.
